Title:
【発明の名称】強磁性材料の切削加工からの残滓を再生する方法および装置
Document Type and Number:
Japanese Patent JP3270071
Kind Code:
B2
Abstract:
A device with which grinding residues, that is swarf which is produced in the working of ferromagnetic materials, can be treated is described. Grinding residues of this type are still associated, in particular, with oil and water and are, in this device, placed in a separating tank (14) which contains a detergent substance or washing solution (51). The oil adhering to the grinding residues is dissolved in this separating tank (14) by mixing and stirring. Subsequently, in a first phase, permanent magnets (17) are used to generate on the tank walls magnetic fields in which the ferromagnetic constituents attach themselves to the residues.
The further constituents can now be passed through a filter (18) and there filtered out of the washing solution. After these constituents have been removed, the magnetic field is switched off. The ferromagnetic constituents are now returned to the washing solution and are passed with the washing solution into this filter (18) or another filter (19), there filtered out and dried. The washing solution is subsequently passed to a tank (25); recovery of the oil removed from the residues takes place in the latter.
